No. 14/826,843 filed on Aug. 14, 2015 and titled “Wireless Peephole Camera and Door Status Indicator,” as issued on Mar. 6, 2018 as U.S. Pat. No. 9,912,920, which in turn claims the benefit of U.S. Provisional Application No. 62/037,991, filed on Aug. 15, 2014, the entire disclosures of which are hereby incorporated by reference for all purposes.

FIELD OF THE INVENTION

The present invention relates generally to the field of home security, and more specifically to methods and devices to detect and record door status events.

BACKGROUND

Every home, office, apartment, and hotel room has at least one door that separates the interior from the outside world. Many of these doors provide a peephole in the door to allow a person on the inside to securely see through the door without being seen by anyone on the other side.

Conventional peepholes are impossible to use unless a person is actually standing at the door to look through the peephole. Enhancement devices have been created to record images through the peephole, but the user must still interact with the device in order to access the images.

With the worldwide explosion of cell phone ownership, people are much more connected and are used to being instantly informed of events that occur that affect their lives. If a cell phone owner misses a call, the expectation is that the caller will leave a message. Even if that does not happen, the missed call is recorded in a log and can be reviewed by the phone owner at a later time.

Wireless networking technology is also relatively ubiquitous in modern life and allows devices to transmit and receive data without physical connections.

SUMMARY

The present application is directed to methods and devices for detection and notification of door status events. An exemplary device may comprise a mounting bracket coupled to a peephole in a door, and a camera apparatus coupled to the mounting bracket. The camera apparatus may comprise a camera positioned such that the camera is capable of capturing images through the peephole, a sensor capable of sensing a door status event at the door or in proximity to the door, and a wireless transmitter/receiver capable of communicating with a wireless network and transmitting digital information via the wireless network. The camera apparatus may further comprise a central processing unit capable of storing and executing computer code to initiate operation of the camera to capture one or more images visible through the peephole when the door status event sensed by the sensor exceeds a predetermined level.

DETAILED DESCRIPTION

The present application is directed to methods and devices for detection and notification of door status events. Various embodiments bring the same level of notification and identification that users have to come to expect for missed phone calls to status events at their door. Such status events may comprise, for example, a knock on the door, opening or closing the door, inserting a key into a door lock, attempting to operate a door handle, sounds emitted in proximity to the door, heat emitted in proximity to the door, motion in proximity to the door, or any other detectable event or condition.

Various embodiments of a wireless peephole camera apparatus (hereinafter also referred to as the camera apparatus) may comprise, in part, a sensor unit and a camera unit. The camera apparatus may be coupled to the door such that the camera unit is optically aligned with a peephole in the door and any pictures taken by the camera will capture images as are visible through the peephole. Operation of the camera unit may be triggered when an event at, on, or in proximity to the door is sensed by the sensor unit. When the camera unit is operated, one or more images may be taken through a peephole in the door. The images and any ancillary data related to the event may then be transmitted via a wireless network and delivered to a configured delivery endpoint. This endpoint may be, for example, a centralized server for secure data storage, an email account, or a mobile device.

Throughout this specification and the appended claims, anywhere a reference is made to a camera taking one or more images, it is to be understood by one skilled in the art that this may refer to taking a photograph, a digital photograph, more than one photograph or digital photograph, or video of any length. No limitations are to be assumed by any use of the terms photograph, image, picture, or video.

Various embodiments may further comprise a mounting platform to couple the camera apparatus to a standard peephole. Peepholes are typically constructed to be able to be installed by screwing together an interior portion (that is, the portion of the peephole position on the interior side of the door) and an exterior portion (that is, the portion of the peephole positioned on the exterior side of the door) through a hole drilled in a door. The mounting platform may comprise a bracket adapted to receive the interior portion of the peephole as the peephole is assembled as described in more detail below, creating a solid mounting platform for the mounting of the camera apparatus.

Various embodiments of the bracket may contain magnets dispersed around the peephole that match oppositely charged magnets on the camera apparatus itself. Coupling the camera apparatus to the bracket may allow the camera to be positioned correctly over the peephole and additionally allow the camera apparatus to be conveniently and easily removed from the door without any disassembly. The magnetic coupling method provides for convenient recharging of the camera apparatus or for removing the camera apparatus to look through the peephole in the conventional fashion.

Another embodiment of the bracket, also adapted to receive the interior portion of the peephole, may use a resistance fit to couple the camera apparatus to the door. Instead of using the magnets, this bracket securely fits around the outer shell of the main device. This embodiment also provides for correctly positioning the camera over the peephole and allowing the camera apparatus to be conveniently and easily removed from the door without any disassembly.

The camera apparatus, according to various embodiments, may be capable of detecting when it is attached to or removed from the bracket, so the end user can also be notified of such an event. Additionally, the device may monitor its power level and emit notifications when power is low and recharging is necessary, or when it a full recharge has been achieved.

Turning now to the drawings, FIG. 1 illustrates various components of an embodiment of the wireless peephole camera apparatus 20. The camera apparatus 20 may comprise a circuit board 5 upon which a power supply 4, contact switch 6, a wireless transmitter/receiver 7, central processing unit 8, sensor 9, and camera 10 are coupled, mounted, or attached. The camera 10 may be capable of recording one or more images or video through a standard door peephole eyepiece 14 (the interior portion of the peephole) and the door peephole lens 15 (the exterior portion of the peephole) installed in a hole 22 in a door 16 (see FIG. 2). The camera 10 may be in communication with and capable of being activated and controlled by the processing unit 8. The processing unit 8 may also receive the images captured by the camera 10 and may be capable of storing those images in memory (not shown) and processing those images. The contact switch 6 may determine when a connection is initiated or broken to a door mounting bracket 13, and may be in communication with and capable of triggering the processing unit 8 when the camera apparatus 20 is removed from the mounting bracket 13. Similarly, the sensor 9 may be capable of detecting movement of the door 16 to which the door mounting bracket 13 and camera apparatus 20 are coupled (for example, a door 16 open/close event) as well as impacts on the door 16 (for example, a person knocking on the door 16). A door status event, if of sufficient intensity, may trigger the processing unit 8. A knock event, for example, may cause the processing unit 8 to initiate the camera 10 to capture one or more pictures through the peephole 14, 15. Any data collected from an event may be communicated to a configured endpoint through the wireless transmitter/receiver 7. The power supply 4 may be electrically coupled to the circuit board 5, which in turn may distribute power to the other components coupled to the circuit board 5.

The camera apparatus 20 may further comprise a translucent status LED ring 3. Although not shown in FIG. 1, the circuit board 5 may comprise one or more LEDs (or other light emitting devices as known in the art) to visually represent an operating status of the camera apparatus 20 to the user. For example, the LEDs may communicate a power level and wireless connection status of the camera apparatus 20 to the user. The circuit board 5 and status LED ring 3 may be contained within a housing comprised of a power supply housing 2 and a housing lid 11. The power supply housing 2 and the housing lid 11 mate with the status LED ring 3 positioned therebetween to form an enclosure for the circuit board 5. The power supply housing 2 may be further partially covered by a decorative, semi-translucent housing base 1.

In various embodiments, the processing unit 8 may comprise software or other code or firmware stored in memory (not shown). This software may control the operation of, and allow communication with, the power supply 4, contact switch 6, wireless transmitter/receiver 7, sensor 9, and camera 10. The sensor 9 may emit a signal to the processing unit 8 related to a door status event. The software may further comprise an algorithm to analyze the signal and determine whether the signal indicates a door status event of significant magnitude to trigger further operation. For example, one door status event is a knock on the door 16. The knock causes vibrations in the door 16 which may be sensed by the sensor 9. However, many events may cause some level of vibration in the door 16, but which are not knocks on the door 16. The algorithm may analyze the signal to determine whether the sensed vibrations are a knock on the door 16 which warrants further action, or merely some other event that caused vibration in the door 16 but is not a knock. Multiple algorithms may reside in memory to analyze the signal from the sensor 9 for multiple types of door status events.

FIG. 2 illustrates various embodiment of coupling the door mounting bracket 13 to the door 16. The door mounting bracket 13 may be adapted to couple securely to (and be flush against) the door 16. A hole 50 in the door mounting bracket 13 may be sized to allow a standard peephole, comprising the peephole lens 15 and the peephole eyepiece 14, to be threaded or inserted through the hole 24. Various embodiments may further comprise a peephole eyepiece adaptor 12, which may allow for peepholes of various diameters to be accommodated, and also has a hole 51 to allow the peephole eyepiece 14 to be threaded or inserted through the hole 51. Only the peephole eyepiece adaptor 12 and the door mounting bracket 13 are coupled to the door 16 such that they are not readily removable. The camera apparatus 20 may securely fit into the door mounting bracket 13, but may be removed as a single unit without having to unscrew the peephole eyepiece 14 or removing the door mounting bracket 13 from the door 16.

In various embodiments as illustrated in FIG. 2, the door mounting bracket 13 may comprise a mounting surface 44 having a peripheral edge 52. The door mounting bracket 13 may further comprise sidewalls 45 extending from the peripheral edge 52 generally perpendicular to the mounting surface 44. A receiving space 48 may be formed between the mounting surface 44 and the sidewalls 45. The mounting bracket 13 may further comprise a coupling device 40, such as a magnet, a latch, a plug or socket, or other coupling device as known in the art. In addition, the mounting bracket 13 may comprise an alignment member 42. The housing lid 11 may comprise a coupling surface 46 having a peripheral edge 53. The housing lid 11 may further comprise sidewalls 47 extending from the peripheral edge 53 generally perpendicular to the coupling surface 46. An insert 49 may be formed by the coupling surface 46 and the sidewalls 47. The insert 49 may be adapted for releasable placement in the receiving space 48. The housing lid 11 may further comprise a coupling device 41, such as a magnet, a latch, a plug or socket, or other coupling device known in the art. Coupling device 40 and coupling device 41 may be the same or may be different. For example, both coupling devices 40, 41 may be magnets. In other embodiments, one of the coupling devices 40, 41 may be a magnet and the other a metal plate. In still other embodiments, one of the coupling devices 40, 41 may be a plug and the other a socket. Any common or different devices for the coupling devices 40, 41 are within the scope of the present disclosure. Coupling device 40 and coupling device 41 may act together to couple the housing lid 11 to the mounting bracket 13 when the insert 49 is placed in the receiving space 48. In addition, the housing lid 11 may comprise a guide member 43 that engages the alignment member 42 to align the housing lid 11 relative to the mounting bracket 13 when the insert 49 is placed in the receiving space 48. When the guide member 43 engages the alignment member 42, the camera 10 within the housing lid 11 may be optically aligned with the peephole 14, 15 mounted in the hole 50 of the mounting bracket 13 and the hole 51 of the peephole eyepiece adaptor 12.

FIG. 3 illustrates various embodiments of the camera apparatus 20 comprising a directly wired power source. In contrast to FIG. 1 in which power is supplied by a battery 4, the embodiments of FIG. 3 comprise a plug assembly 21 for connection directly to a standard AC outlet. The plug assembly 21 may further comprise an AC/DC converter, or the converter may reside on the circuit board 5. The directly wired power source may allow the camera apparatus to operate continuously without recharging the battery 4. While the status LED ring 3 may not be required to indicate battery 4 charging/recharging status, the status LED ring 3 may indicate that the camera apparatus 20 is receiving power and whether the electronic systems are function properly.

FIG. 4 illustrates an alternate embodiment for coupling the camera apparatus 20 to the door 16. In this embodiment, a magnetic mounting plate 23 having a back surface 30 and a front surface 31 opposite the back surface 30 may be coupled to the door 16 by the peephole 14, 15 as described previously for the mounting bracket 13. When the magnetic mounting plate 23 is coupled to the door 16 (or any other surface), the back side 30 may be in contact with the door 16, and the front side 31 may be positioned away from the door 16. The magnetic mounting plate 23 may comprise a plurality of embedded magnets 24 at intervals around the magnetic mounting plate 23. The magnets 24 may be of sufficient strength to securely hold the camera apparatus 20 in a fixed position to the door 16, so that images may be captured with the camera 10 through the peephole 14, 15. Oppositely charged magnets 25 may be embedded in the mounting bracket 13. A magnetic indicator switch (not shown) on the mounting bracket 13 may detect changes in a magnetic field between the magnets 25 on the mounting bracket 13 and the magnets 24 on the magnetic mounting plate 23, and may signal the processing unit 8, when the magnetic connection between magnets 23 and magnets 25 is initiated or broken.

In various embodiments, the magnetic mounting plate 23 may further comprise raised shaped protrusions 28, upon which the magnets 24 may be mounted. Although other shapes are certainly possible, FIG. 4 illustrates conical-shaped protrusions 28. The mounting bracket 13 may comprise indentations 29, upon which magnets 25 may be mounted. The indentations 29 may be spaced to coincide with the spacing of the protrusions 28 such that each protrusion 28 engages an indentation 29 when the mounting bracket 13 is placed in proximity to the magnetic mounting plate 23. The mounting plate 23 may have a feature, such as first hole 34, and the mounting bracket may have a feature, such as second hole 35. When the protrusions 28 engage the indentations 29, the first hole 34 may be concentrically aligned. When the camera apparatus 20 is placed in the mounting bracket 13, the camera 10 may be optically aligned with the concentrically aligned first hole 34 and second hole 35, as well as the peephole 14, 15.

In various embodiments, neither the mounting plate 23 nor the mounting bracket 13 may comprise magnets. In these embodiments, the mounting plate 23 and the mounting bracket 13 may be coupled together by a resistance fit between the protrusions 28 and the indentations 29, a key and slot locking mechanism within the protrusions 28 and the indentations 29, or the like.

Various embodiments capable of mounting on a glass surface 27 are illustrated in FIG. 5. A double-sided adhesive 26 of any type known in the art may be coupled to the mounting bracket 13, which is then coupled to the glass surface 27. Although the adhesive 26 is illustrated as a continuous ring in FIG. 5, and appropriate shape or type of adhesive 26 as is adequate for the situation may be used. For example, the adhesive 26 may comprise multiple strips or multiple circles, squares, or other shapes. In addition, the adhesive 26 may be a liquid or semi-liquid material dispensed from a tube, bottle, or other container.

FIG. 6 describes a logic flow 600 of an embodiment of the wireless peephole camera apparatus 20 for detecting a door status event (specifically, a knock on the door 16) according to various embodiments. The camera apparatus 20 begins in a sleep state, Step 601. The flow 600 is initiated in Step 602 by the sensor 9, an accelerometer in this particular embodiment, registering a vibration event of sufficient strength to qualify as a “knock” (or a “tap” as specified in FIG. 6) Any detected vibration below a predetermined “knock” threshold may be ignored and the sensor 9 may return to its monitoring state, Step 601. When a valid knock is registered by the sensor 9, the sensor 9 may send a signal to the processing unit 8 to wake up and trigger the camera 10 to record one or more images (or a video stream) through the peephole 14, 15 in Step 603. If the camera 10 is able to record images, the processing unit 8 may process those images to determine if any are of sufficient quality to forward to the user and/or pick the “best” image by any available algorithm in Step 604. If no valid pictures are available, a “no picture” notification may be generated in Step 605. Regardless of whether an image is obtained, once a knock is detected, the processing unit 8 may engage the wireless transmitter/receiver 7 in Step 606 and the wireless transmitter/receiver 7 may, in turn, attempt to connect to a configured wireless network in Step 607. The connection may be re-attempted upon failure in Step 608 until either a connection is established or a configured number of retries, “N,” is surpassed. If no connection can be established, an error may be recorded in Step 609, and the camera apparatus 20 may return to the sleep state, Step 601. If the connection is established, any collected data for the knock event, including one or more pictures taken by the camera 10 may be sent to the configured endpoint through the wireless network in Step 610. In this embodiment, the data may be uploaded to a centralized server, hosted in a cloud network for high availability and reliability. Alternatively, at Step 610 the image and notification may be sent directly to a computing device such as a smartphone, laptop computer, desktop computer, or the like. Upon receiving new knock data from the camera apparatus 20, the server may send a push notification to the end user's mobile device or email account in Step 611. Once the data are uploaded, the camera apparatus 20 may return to its initial, low-power sleep state, Step 601, waiting for another event.

FIG. 7 describes the logic flow 700 of an embodiment of the wireless peephole apparatus 20 detecting a door status event (specifically, a door 16 open or close event). The camera apparatus 20 begins in a sleep state, Step 701. The flow 700 is initiated in Step 702 by the sensor 9, an accelerometer in this particular embodiment, registering spatial movement of the door 16 sufficient to qualify as a door 13 open or close event. Any detected movement below a predetermined movement threshold may be ignored and the sensor 9 may return to its sleep state, Step 701. When a valid movement event is registered by the sensor 9, the sensor 9 may send a signal to the processing unit 8 to wake up and engage the wireless transmitter/receiver 7 in Step 703. The wireless transmitter/receiver 7 may, in turn, attempt to connect to the configured wireless network in Step 704. The connection may be re-attempted upon failure in Step 705 until either a connection is established or a configured number of retries, “N,” is surpassed. If no connection can be established, an error may be recorded in Step 706, and the camera apparatus 20 may return to the sleep state, Step 701. If the connection is established, any collected data for the motion event may be sent to the configured endpoint through the wireless network in Step 707. In this embodiment, the data may be uploaded to a centralized server, hosted in a cloud network for high availability and reliability. Alternatively, at step 707, the collected data may be sent directly to a computing device such as a smartphone, laptop computer, desktop computer, or the like. Upon receiving new movement data from the camera apparatus 20, the server may send a push notification to the end user's mobile device or email account in Step 708. Once the data are uploaded, the camera apparatus 20 may return to its initial, low-power sleep state, Step 701, waiting for another event.

Although not shown in FIG. 7, the processing unit 8 may also communicate with the camera 10 and initiate operation of the camera 10 to take one or more images once a valid movement event is detected. The captured images may be useful to identify the person opening or closing the door, particularly if the person is engaging in illegal activity.

In the embodiments described above in relation to FIGS. 6 and 7, the sensor is an accelerometer capable of detection vibration and spatial movement. While knocking and opening and closing are common door status events, one skilled in the art will readily recognize that the present disclosure is in no way limited by these examples. The accelerometer may detect vibrations caused by inserting a key into a door lock, or vibrations caused by someone attempting to operate a door handle. In either case, the camera 10 may take an image of the person attempting to open the door 16, and the image may then be sent to the user as described previously.

Further, the present embodiment is not limited in any way by the type of sensor 9. In various embodiments, the camera apparatus 20 may be configured with a sensor 9 adapted to sense any movement or condition that may occur at, on, or in proximity to the door 16. For example, the sensor 9 may sense heat. Such a sensor 9 may be useful for detecting the presence of a person in proximity to the door 16, or even a fire in proximity to the door 16. The camera 10 may then take an image of the person or condition in proximity to the door 16, and the image may then be sent to the user as described previously.

In other embodiments, the sensor 9 may sense sounds. The camera 10 may take an image when a loud sound is detected in proximity of the door 16, and the user may use the image to determine if any danger is present in proximity to the door 16.

In still other embodiments, the sensor 9 may sense motion. The camera 10 may take an image when motion sufficient to indicate a person is in proximity to the door 16. Such an image may be useful to identify a burglar or vandal that was in the area. Further, the camera 10 may be in a constant activation mode (particularly with the wired power source embodiments as depicted in FIG. 3) and the user may access a digital feed from the camera 10 (such as by accessing an application on a smartphone) to remotely look through the peephole 14, 15 when the motion sensor is activated. The smartphone application or other software may comprise facial recognition capabilities to identify any persons visible to the camera. This remote capability to look through the peephole 14, 15 may also be available even if the camera apparatus 20 lacks a sensor.

In yet other embodiments, the sensor 9 may sense the presence of metal. The camera 10 may take an image when a person comes in proximity to the door 16 and metal is sensed sufficient to be a weapon. The user may then use the image to identify whether the person is safe to allow in, or for later identification of a burglar or vandal.

Additional embodiments may comprise a sensor 9 to sense electromagnetic radiation, which may be in the form of a flashlight being shined on the door 16. Since shining a light on a door is not a typical activity, when such an event occurs, the user may view the image taken by the camera 10 to help identify the person with the flashlight and perhaps determine whether the person committed any illegal acts.

As is now obvious to one skilled in the art, the camera apparatus 20 may be equipped with one or more sensors 9 to sense any type of motion, activity, event, or condition that occurs at, on, or in proximity to the door 13. The specific embodiments presented herein are intended as being exemplary and not limiting in any way the sensory capabilities of the camera apparatus 20.

FIG. 8 is a flowchart of an exemplary method 800 for detection and notification of a door status event. At Step 805, a camera apparatus 20 may be coupled to a peephole 14, 15 in a door 16 such that the camera unit 10 is optically aligned with the peephole 14, 15. The camera apparatus 20 may comprise a sensor unit 9, a camera unit 10, a wireless transmitter/receiver unit 7, and a processing unit 8. The sensor unit 9 may sense a door status event at, on, or in proximity to the door 16 at Step 810. At Step 815, an algorithm stored in memory in the processing unit 8 may be initiated. The algorithm may determine whether the sensed event exceeds a predetermined threshold. The camera unit 10 may be activated at Step 820 when the sensed event exceeds the predetermined threshold. The camera unit 10 may record one or more images visible through the peephole 14, 15.

FIG. 9 is a flowchart of an exemplary method 900 for detection and notification of a person at a door 16. At step 905, a camera apparatus 20 comprising a sensor unit 9 comprising an accelerometer, a camera unit 10, a wireless transmitter/receiver unit 7, and a processing unit 8 may be coupled to a peephole 14, 15 in a door 16 such that the camera unit 10 is optically aligned with the peephole 14, 15. At Step 910, the sensor unit may sense vibration or movement of the door 16 caused by a knock on the door 16 or opening or closing the door 16. At Step 915, an algorithm that is stored in memory in the processing unit 8 may be initiated. The algorithm may determine whether the sensed vibration or movement exceeds a predetermined threshold. The camera unit 10 may be activated at Step 920 when the sensed vibration or movement exceeds the predetermined threshold. The camera unit 10 may record one or more images visible through the peephole 14, 15. At Step 925, a Wi-Fi connection to a computer network may be established by the wireless transmitter/receiver unit 7. The images taken by the camera 10 may be uploaded to the network. The uploaded images may be delivered to an electronic device at Step 930.

According to various embodiments, the camera apparatus 20 may communicate with a cloud-based computing environment that collects, processes, analyzes, and publishes datasets. In general, a cloud-based computing environment is a resource that typically combines the computational power of a large grouping of processors and/or that combines the storage capacity of a large group of computer memories or storage devices. For example, systems that provide a cloud resource may be utilized exclusively by their owners, such as Google™ or Yahoo!™, or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefits of large computational or storage resources.

The cloud may be formed, for example, by a network of web servers with each server (or at least a plurality thereof) providing processor and/or storage resources. These servers may manage workloads provided by multiple users (e.g., cloud resource customers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depend upon the type of business associated with each user.

FIG. 10 illustrates an exemplary computing system 1000 that may be used to implement an embodiment of the present technology.
